The Tokina TM22Z1022AIPN offers a 10-220mm focal length, which translates into a 22x optical image magnification. Users will appreciate the quick and accurate way this lens responds to commands sent by a CCTV lens controller device. A motorized zoom lens is a grand idea for applications looking to use a single fixed CCTV camera to cover a wide area and at the same time have the ability to zoom in for a closer look when necessary.
